Be it known that I, MICHAEL residing at ll Lime Grove, Handsworth,

Birmingham, in the county of \Warwick,

England, foreman wire-drawer, have invented certaln new and useful Improvements in or Pertaining to Gontinuous-Wire- 5 Drawing Machinesfof which the following is a specification.

, This invention relates to continuous wire a machine which is of a very simple character whlch occupies a small amount of space and which provides for easy access to each winder or block;

According to the present invention a series.

of winders is arranged in conjunction with acterized in that they increase in diameter from the smallest to the largest. .Advant-ageously the winders are arranged around the main drum in such a manner that the wire successively passes around each winder commencing at the smallest and finishing around the largest or central drum. By this arrangement of winders, the spindles on which they are mounted may be rotated at the same number of revolutions per minute and yet compensate for the increase in the length of wire In order that this invention may be clearly understood and more readily carried into practice, reference may be had to the ap pended explanatory three sheets of drawings-upon which Figure 1 1s an elevation of a machine according to the invention. Fig. 2 is a plan of the machine shown in Fig. 1. Fig. 3 is a plan showing gear wheels for driving the winders. Fig. 4 is a side elevation ofone form of drawing plate or die. Fig. 5 is an end elevation of the drawing plate or die shown in Fig. 4. r

In this invention a suitable table a is provided and conveniently in the center thereof Specification of manhunt. Application filed February-a, 1912.- ssmii 1 i J ROOKI}; a: subject of the King of Great Britain,

. A convenient meth'od of rotatingthe number of revolutions winders or blocks m may consist in secur-.

ing them upon vertical spindles n suitably journaled in the table a of the machine and supported at their lower extremities by brackets 0, provided with bearings p and attached conveniently set screws g to the same standards rupon which the top table and the cross bar aforementioned are mounted.- Suitable loose collars a may be secured to the vertical spindles n to prevent their upward movement, a similar collar t being also attached to the central mainshaft for rotating the subsidiary vertical spindles from the main vertical shaft takes the form of a spur wheel u on the main shaft which gears with smaller spur wheels '0 on the Sub-.

sidiary spindles, the gear wheels on the latter being all-of the same diameter and mes ing with the central wheel u;

Intermediate each pair of winders is dis posed a drawing plate or .-die .Jw through which the wire passes to ually reduce it in size; the wire passing around one winder, through the die, and onto the next, winder; thence through the next die and so on throughout the entire series finishing around the largest or central drum. To I pull the wire through at starting, a pair of grippers w may be attached to the extremitg of a fulcrum lever y, said lever being acte A convenient method of upon at a short distance from its fulcrum by a suitable cam a mounted on the main vertical shaft in such a manner that the extremity to which the grippers are attached has an amplified movement as compared with the lift of the cam. v

The dies comprise die. supports for suitable dies which are attached thereto, and the dies mayconsist of a bar of metal having oneor several holes therethrough of different sizes, held in place bythe die sup'- ports. In some embodiments of the invention, I may use dies at, and 3 The die w would only be used in initially starting the machine.

In starting the drawing operation, the operator first files, or otherwisereduces the end of the wire to a smaller diameter, and passes it through the first; die which, of course, would have the largest hole, and which is indicated at m. The gri pers w, on

the lever would be attached to t e inserted the end of the wireand drawing it through the second die by the grippers w, the second die being placed in the support :12, for this operation. When a suflicient length of wire.

has been drawn'through the second die this is transferred to its bearer or support, :0 after the intermediate length of wire between the first and second dies has been passed one or more times around the first winder. By this process all of the dies have to be threaded and placed in position, including a final die, at 3/ so that the wire is drawn through each die by the grippers a: and lever 11 After the dies have all been supports, with the intermediate lengths of wire wound around the respective winders, then the endof the wire is secured to the central drum and the wire drawing continues automatically until the entire length of wire supply has been drawn through.

VVha't I claim as mly invention and desire to secure by Letters atent is A wire drawing machine comprising in combination, a series of winders mounted to rotate about difl'erent axes and being of successively increased size from the first or starting to the last or delivery winder, devices for reducing the wire during its pasthreaded, and transferred to their proper sage from one winder to the other, and

mechanisms for driving said Winders at the same numberv of IGVOlHtlOIlS" per minute whereby the increasing surface speed of successive winders serves to take up wire length increase of the reduced Wire, substantially as described.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
